摘要

在巴西东南部圣保罗州Jaboticabal进行了一项长期试验(2013年至2017年),研究了潮湿热带地区通过施肥处理过的污水排放(TSE)水平,以评估TSE对土壤肥力的影响以及Oxisol盐碱化和重金属污染的可能性。在4年试验期间,在灌溉深度(0、11、60和100%)施用4个TSE水平的黑斑草(Urochloa brizantha)。在整个实验期间监测TSE的化学成分。在4年试验结束时,对0 ~ 0.10 m和0.10 ~ 0.20 m土层的重金属水平和土壤肥力进行评价。使用TSE施肥不会增加土壤中潜在有毒元素(As、Cd、Cu、Hg、Mo、Ni、Pb、Se和Zn)的浓度,因为它们在流出物中的浓度很低。高TSE水平(60%和100%)也观察到较高的Na浓度。然而,TSE对钠的吸附速率较低,没有产生土壤盐碱化和固化的潜力。与对照相比,TSE水平的施肥提高了土壤肥力,土壤中磷含量和碱基饱和度提高了10%以上。根据土壤和流出物的化学性质评价,本长期研究表明,在潮湿热带地区,推荐在种植牧草的粘土土壤上通过施肥施用TSE。

Impact of treated sewage effluent on soil fertility, salinization, and heavy metal content
: A long-term experiment (2013 to 2017) of treated sewage effluent (TSE) levels via fertigation in a humid tropical region was installed in Jaboticabal, state of São Paulo, Southeast of Brazil, to evaluate the impact of TSE on soil fertility and the potential for salinization and heavy metal contamination of an Oxisol. The area was cultivated with Urochloa brizantha under the application of four TSE levels at the irrigation depth (0, 11, 60, and 100% TSE) during the four years of the experiment. The TSE chemical composition was monitored throughout the experimental period. The heavy metal levels and soil fertility were evaluated in the 0-0.10 and 0.10-0.20 m layers at the end of the four years of the experiment. Fertigation using TSE did not increase the concentration of potentially toxic elements (As, Cd, Cu, Hg, Mo, Ni, Pb, Se, and Zn) in the soil due to their low concentration in the effluent. A higher Na concentration was also observed at high TSE levels (60 and 100%). However, the sodium adsorption rate in the TSE was low, generating no potential for soil salinization and sodification. Fertigation with TSE levels increased soil fertility, increasing by more than 10% the P content and base saturation in the soil compared to control. According to the chemical attributes evaluated in the soil and effluent, this long-term study showed that TSE application via fertigation in humid tropical regions on clayey soils cultivated with forage grasses is recommended.
